TIRE FOR VEHICLE-WHEELS.

SPECIFICATION forming part of Letters Patent N0. 667,348, dated February5, 1901.

Application filed June 27, 1900.

To all whom it may concern:

Be it known that I, FERDINAND W. STARR,

of Springfield, in the State of Ohio, have invented certain new anduseful Improvements in Tires for Vehicle -Wheels; and I do herebydeclare the following to be a full, clear, and

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to an improvement in; tires, and more particularlyto such'as have a yielding tread, one object of the invention being toconstruct a compound tire comprising a uniformly strong base orfoundation por- I 5 tion and a tread portion and to so construct saidbase portion that it can be readily secured to a channel-iron rim bymeans of fastening devices passed transversely through it anywhere alongits length, and thereby dispense with the usual circumferentialtension-Wires for holding the tire Within a channel-ironrim and to makethe same accessible to the general public by reason of its simpleapplication.

A further object is to produce a tire which 2 5 shallbe simple inconstruction, comparatively cheap to manufacture, and which shall beeffectual in all respects in the performance of the required functions.

With these objects in View the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is 5 a longitudinal sectionalview illustrating my invention. Fig. 2 is a cross-section. Figs. 3, 4:,5, 6, and 7 are views of modifications.

A represents a portion of the channel-iron rim of a wheel, which mayvary to suit the 0 shape of the improved base it is to hold; B, theframe-base or foundation portion of the tire, adapted to fit and to besecurely held within the channel-iron rim, and Orepresents an elastic oryielding tread secured to the said base portion in any preferred manner.

The novelty of my invention resides more particularly in theconstruction or provision of a uniformly strong base portion in or fortires and the manner of securing it to the channel-iron rim, Whether thesame be united Serial No. 21,804. (No model.)

to the tread C before or after securing the same to the channel-iron.

In the form of the invention shown in Figs. 1 and 2 the base portion Bof the tire C0111- prises a series of transversely corrugated or crimpedmetallic ribbons or strips 1, between which fiat metallic strips 2areinterposed, and the whole is wrapped with cord, canvas, cloth, orother suitable flexible material 3, which acts to muffle and cushion andto securely 6o bind, incase, or embrace the metallic interior of thesaid base portion and also allows it to circumferentially fit varyingdiameters of channel-rims. The base or foundation portion thusconstructed, and whether united with the tread portion first or last, isfitted into the channel-iron rim A and held securely therein by means oftransverse screws or pins 4, which pass through the flanges of thechannel-iron and said binding or covering and through the perforationsformed by the corrugated strips. It will be observed that by theemployment of corrugated strips 'numerous positive holding-ridges,perforations, or guideways for the transverse fastening devices arecheaply provided without boring or drilling.- In fact, a continuousseries of such securing-points, perforations, or guideways are formedthereby, so that the securing-pins can be safely passedthrough the baseportion at any point without limitation or danger of any injury thereto.In order that the fastening pins or screws be made to pass freelythrough the portion B Without conflict with the edge of the straight orflat metallic strips, the pins should be pointed, and the edges of thestrips may be beveled or sharpened, as at 5, Fig. 2, and the holes inthe flanges of the channel-iron rim should be countersunk for a likepurpose, as shown. The tread portion is uniformly secured to the baseportion B by means of cement or glue, by vulcanizing, or in any otherpreferred manner, and said tread portion may consist of rubber or otheryielding material and may embrace the base por- 5 tion to any desiredextent.

It is not absolutely necessary that a series of corrugated strips beemployed, as one will serve as guideways and holder for the pins, asshown in Fig. 3, and only one flat strip may mo be used, or a singlecorrugated strip with two flat strips may be used, as shown in Fig. 4,or two corrugated strips with a flat strip between them may be employed,as shown in Fig. 5, or corrugated strips without flat strips may beused, as in Fig. 6, or the strips may all be flat and of other materialthan metalwood, for instance, as in Fig. 7, inwhich case the pointedtransverse fastening devices 4 would readily enter between the flatstrips and binding, and the said binding of the baseportion B wouldyield sufficiently to let them passand still securely grip them.

Various other changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting itsscope as relates to a uniformly strong base portion for tires, and I donot wish to limit myself to the precise details of construction hereinset forth only, for it will no doubt be evident that even a single stripof wood or other material may be wrapped with cord, cloth, canvas, oreven wire in order to bind and produce a strong muffled base portionwhich the insertion of the securing-pins would not split nor separate inuse and which would be likewise capable of being safely perforatedanywhere along its length for the insertion of said securing-pins, whichis one of the important features and objects of my invention--namely, toprovide a base or foundation portion which shall be capable of beingsafely secured within a channel-iron rim anywhere along its length, ashereinbefore stated.

intended to be made practically waterproof,

ering, and also that this compound tire may be constructed straight,circular, or spiral lengthwise, by which is meant that the treadportionmay be united to or built up with the base portion while held togetherin a form, mold, or otherwise. In the latter case the diameter of themold may be less than the wheel for which the compound tire is intended,and in opening out the spiral or coil form of the tire thus constructedwould tend to condense the yielding outer tread portion, and thus'in ameasure increase its wearing.

quality and also give it a tendency to hug the channel-iron wheel-rim byreason of the eX- The peculiar advantages arising out of the novelconstruction of said base portion are that it will bend readily in therequired direction, that It may also be stated that said base portionis.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a channel iron rim, of a tire comprising a baseor foundation portion consisting of a strip and a binding or wrapping,adapted to permit the passage of transverse fastening devices at anypoint, and a tread portion secured to said base or foundation portion,substantially as set forth.

2. The combination with a channel-iron rim, of a tire comprising a baseportion consisting of strips, a tread portion secured to the baseportion and fastening devices passing transversely through thechannel-iron rim and between't-he strips of the base portion,substantially as set forth.

3. The combinatiouwith a channel-iron rim, of a tire comprising a baseportion and a tread portion united to the base portion, said baseportion comprising strips bound with flexible material and pointedtransverse fastening devices passing through the flanges of thechannel-iron and through the base portion, between the strips thereof,substantially as set forth.

4. In a tire, a base portion having a corrugated strip therein adaptedto form a continuous series of connecting-guideways for transversefastening devices, substantially as set forth.

5. In a tire, a base portion having strips passing longitudinallythrough it, said strips being so disposed relatively to each other as toreceive transverse fastening devices between them at any point,substantially as set forth.

6. In a tire, a base portion having a corrugated strip ofmetal and aflat strip of metal therein, substantially as set forth.

7. In a tire, the combination with a channel-iron rim, of a base portioncomprising corrugated strips, interposed flat strips having bevelededges, fastening devices passing transversely through the flanges of thechannel-iron and through grooves of a corrugated strip, and a treadportion secured to the base portion, substantially as set forth.

8. In a tire, the combination with a channel-iron rim, of a base portioncomprising corrugated strips, a wrapping of flexible material inclosingsaid strips, fastening devices passing transversely through the flangesof the channel-iron rim and through grooves of a corrugated strip, and ayielding tread portion secured to the base portion, substantially as setforth.

9. In a tire, the combination with a channel-iron rim and a treadportion, of a base portion to which said tread portion is secured, saidbase portion being disposed between the tread and the rim and said baseportion having unlimited transverse connecting-guideways for transversefastening devices which pass through said base portion and the flangesof the channel-iron rim, substantially as set forth.

10. A base portion for a tire comprising corrugated strips and a bindingof flexible material entirely inclosing and enveloping said strips,substantially as set forth.

11. The combination with a channel-iron rim, the flanges of which aremade with holes and said flanges beingcountersunk around said holes, ofa base portion consisting of strips, transverse fastening devices havingpointed ends, passing through said flanges and base portion and a treadportion secured to the base portion, substantially as set forth.
